CATERPILLAR-BELT-TENSIONER

Part 217-8938 is a Caterpillar accessory belt tensioner, built to the same spring-tension and pivot tolerances as the original equipment. Its function is straightforward: apply constant, correct pressure to the drive belt so it neither slips under load nor over-tensions the driven pulleys' bearings. Fleet operators running Cat equipment through long shifts typically replace this on a scheduled interval rather than waiting for failure. Orange.net.za has it in stock for fast delivery across South Africa.
